What is ISO/TS 8062-2 – Dimensional and geometrical tolerances for moulded parts about?  

Geometrical Product Specifications (GPS) is the international symbol language used to express tolerances in technical drawings. This global specification language enables the drawing of a component developed in one country to be sent to another country, where it can be understood and the component can be manufactured. It ultimately aids in easy and efficient production of parts and products. 

ISO/TS 8062-2 gives the rules for geometrical dimensioning and tolerancing of final moulded parts and parts machined out of moulded parts. It also gives rules and conventions for the indications of these requirements in technical product documentation and specifies the proportions and dimensions of the graphical symbols to be used. 

ISO/TS 8062-2 provides symbols which may be used to identify the relative completeness of the moulded features and parts. These graphical symbols should not be confused with the graphical symbols for surface texture according to ISO 1302, which are notably larger.  

Who is ISO/TS 8062-2 - Dimensional and geometrical tolerances for moulded parts for?  

ISO/TS 8062-2 on dimensional and geometrical tolerances for moulded parts is relevant to:  

• Organizations involved with foundry engineering and castings 
• Manufacturing industry 
• Product design engineers
• Entities involved in technical drawings 
• Industries including but not limited to automotive, consumer goods, machinery etc 
• Quality control and testing authorities 

Why should you use BS ISO/TS 8062-2 - Dimensioning and tolerancing of non-rigid parts?  

The need for quality within manufacturing is of utmost importance and it is necessary that the design and functionality of a part be accurately communicated between design, inspection and production teams. In this regard, geometric dimensioning and tolerancing is a system containing symbols and standards that help communicate this design intent and its permitted tolerance for variation.  

ISO/TS 8062-2 is to be regarded as a complementary process-specific tolerance GPS standard. It influences chain links 1, 2 and 3 of the chain of standards on mouldings. 

ISO/TS 8062-2 provides the best industry guidance on designation on drawings, drawing type indicator, drawing indications, indication of general tolerances, dimensioning and tolerancing. 

Compliance with ISO/TS 8062-2 can aid in improved design accuracy of moulded parts, ultimately playing a positive role in optimizing production and enhancing cost-effectiveness. As a result, you can ensure the moulded parts are fit for its intended application.
